T0 if/ZZ 11171/0777/ it may concern:

Be it known that I, PHILIP H. GERHARD, a citizen of the United States, residing'at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Apparatus for Treating Timber; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatuses for the treatment of timber and other material; and it consists in certain novel features of construction, combination, and arrangement of parts hereinafter described and claimed.

The object of my invention is to provide a simple, inexpensive, durable, and efficient apparatus by means of which railroad cross-ties, fence-posts, and the like may be expeditiously and economically treated by immersion in a bath of some preserving liquid.

The above and other objects, which will appear as the nature of my invention is better understood, are accomplished by the construction illustrated in the accompanying drawings, in Which-- Figure l is a perspective view of an apparatus constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view through a slightly-modified form of the apparatus, and Fig. 3 is a vertical transverse sectional View taken on the line 3 3 in Fig. 2.

Referring more particularly toFig. l of the drawings, the numeral 1 denotes a container for the liquid preserver with which the beams of timber or other material are to be treated. As shown, this receptacle or container is in the form of a rectangular tank or vat, which has its forward end inclined, as shown at 2,-

to the ends of upper and lower shafts 6 and 7, journaled in bearings 8 upon the front side or section'9 of an inverted-V-shaped frame l0. The opposite side or section 1l of the frame l() is inclined in a reverse direction to the side or section 9, and each of said sides or sections consists of two side beams l2, connected by cross-beams 13. The lower pair of sprocketwheels 5 are located adjacent to the rear end of the tank l, so that the timbers or other objects treated in the latter may be readily lifted upon said chain and engaged with lingers 14., provided at suitable intervals upon its links. The upper pair of sprocket-wheels 5 are disposed adjacent to the upper end of the frame 10, so that the conveyer discharges the timbers upon the downwardly-inclined side or section ll of the frame, which forms a chute or skid. In order to catch and save the preserving liquid which drips from the timbers as they are carried upwardly by the endless elevator, I provide beneath the section 9 of the frame 10 an inclined drip pan or receptacle l5, which has its lower end 16 in communication with the rear end of the tank by means of a connecting-pipe 17, through which the drippings may pass from said pan into said tank.

The elevator may be driven in any desired manner; but I preferably provide upon the shaft 7 a gear 18, which meshes with a pinion 19 upon a shaft 20, journaled in bearings upon the lower portion of the framesection 9. Upon said shaft 20 is secured a band-wheel or pulley 2l, which may be driven by any suitable motor. In the drawings I have shown said pulley 21 connected by a belt 22 to a pulley or belt-wheel 23 upon the crank-shaft of the steam-engine 24. The latter is mounted upon the side of an upright steam-boiler 25, which is located adjacent to the frame 10. The usual steam connections are provided between .the steam-space of the boiler and the steam-chest of the engine-cylinder.

The preserving liquid within the tank 1 may be heated in any desired manner; but I preferably provide a steam-coil or other steamheating device 26 in the bottom of the said tank and connect it by the steam-pipe 27 with the steam-space of the boiler 25, as shown.

IOO

In Figs. 2 and 3 of the drawings I have shown a slightly-modified form of the apparatus, the frame having its side sections 9 and 11 pivotally connected at their upper ends, as shown at 30, sothat they may be folded upon each other, and the lower end of the frame-section 9 having its side bars 12 detachably pivoted, as shown at 31, to the tank 1. This construction permits the frame 10 to be readily removed from the tank 1 or folded over upon the saine, so as to facilitate transportation of the apparatus. It also permits the lower ends ofthe endless elevatorchains'to extend beneath the level of the liquid in the tank 1, so that the timbers or other objects may be readily floated into engagement with the fingers 14 upon said chains. In order to hold the frame-sections 9 and 11 in their open position, any suitable means may be provided. As shown in the drawings, I have pivoted bars 32 upon the side beams 12 of the frame-section 9, as shown at 33, and detachserving liquid which drips from the timbers as they are elevated falls down into the drip pan or receptacle 15 and returns to the tank. The drip-pan 15 (shown in Figs. 2 and 3) is preferably detachably connected, as shown at 35, and its low er open end discharges the liquid falling thereon into the tank 1.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent` is Apparatus for treating timber, comprising a receptacle for the treatment of wood by irnmersion in aliquid preservative, a frame having upwardly-inclined outwardly-converging sides, one of which rises from within the said nesses.
